Alight elastic string, of natural length / and modulus 6 mg, has one end attached to a fixed point o, and to the other end is attached a particle p of mass m. the particle is held at rest at a point a vertically below 0, where 04 = 31/2, and is then released. by energy considerations, or otherwise, show that p is next at rest when it is at a distance 31/4 below 0. show that if the length of the string is i at time i after relcase and before the string becomes slack, then where wa = 6g/l. by making the substitution 1 = y + 1/6, or otherwise, show that the string first becomes slack when 1 271(30).
